Izinyathelo zendlela
1. I-sprocket kufanele ifakwe ku-shaft ngaphandle kokugoba nokujika. Ku-gear assembly efanayo, ubuso bokugcina bama-sprocket amabili kufanele bube sendizeni efanayo. Uma ibanga eliphakathi le-sprocket lingaphansi kwamamitha angu-0.5, ukuphambuka okuvumelekile kungu-1 mm; uma ibanga eliphakathi le-sprocket lingaphezu kwamamitha angu-0.5, ukuphambuka okuvumelekile kungu-2. mm. Kodwa-ke, akuvunyelwe ukuba nomcimbi wokungqubuzana ohlangothini lwamazinyo lwe-sprocket. Uma amasondo amabili ephambukile kakhulu, kulula ukubangela ukuguguleka okungaxhunyiwe kanye nokusheshisa. Kumelwe kuqashelwe ukuhlola nokulungisa ukuphambukisa lapho kushintsha ama-sprocket.
2. Ukuqina kweketanga kufanele kube okufanele. Uma liqinile kakhulu, ukusetshenziswa kwamandla kuzokwenyuka, futhi ibhereyi izogqokwa kalula; uma iketanga likhululekile kakhulu, lizogxuma kalula liphume eketanga. Izinga lokuqina kweketanga yileli: phakamisa noma ucindezele phansi usuka maphakathi neketanga, futhi ibanga eliphakathi kwezikhungo zama-sprocket amabili lingaba ngu-2-3cm.
3. Iketanga elisha lide kakhulu noma linwetshiwe ngemva kokusetshenziswa, okwenza kube nzima ukulilungisa. Ungazisusa izixhumanisi zeketanga kuye ngesimo, kodwa kumele kube yinombolo elinganayo. Iketanga kufanele lidlule ngemuva kweketanga, ingcezu yokukhiya kufanele ifakwe ngaphandle, futhi ukuvulwa kwengcezu yokukhiya kufanele kubheke ohlangothini oluphambene nokujikeleza.
4. Ngemva kokuba i-sprocket isigugile kakhulu, i-sprocket entsha kanye neketanga kufanele kushintshwe ngesikhathi esifanayo ukuqinisekisa ukuthi ine-mesh enhle. Iketanga elisha noma i-sprocket entsha ayikwazi ukushintshwa yodwa. Ngaphandle kwalokho, izobangela i-mesh embi futhi isheshise ukuguguleka kweketanga elisha noma i-sprocket entsha. Ngemva kokuba ubuso bezinyo be-sprocket bugugile ngezinga elithile, kufanele buguqulwe futhi busetshenziswe ngesikhathi (kubhekiselwa ku-sprocket esetshenziswe endaweni elungisekayo). ukuze kwandiswe isikhathi sokusebenzisa.
5. Iketanga elidala alikwazi ukuhlanganiswa nezinye iketanga ezintsha, ngaphandle kwalokho kulula ukukhiqiza umthelela ekudlulisweni kwegesi futhi liphule iketanga.
6. Iketanga kufanele ligcwaliswe ngamafutha okugcoba ngesikhathi somsebenzi. Amafutha okugcoba kumele angene esikhaleni esifanelana phakathi kwe-roller kanye ne-sleeve yangaphakathi ukuze kuthuthukiswe izimo zokusebenza futhi kuncishiswe ukuguguleka.
7. Uma umshini ugcinwe isikhathi eside, uchungechunge kufanele lususwe futhi luhlanzwe ngophethiloli noma ngodizili, bese lugcotshwa ngowoyela wenjini noma ibhotela bese lugcinwa endaweni eyomile ukuvimbela ukugqwala.
Izinyathelo zokuzivikela
Ezimotweni ezine-derailleur yangemuva, setha iketanga libe sesimweni sepheya lamasondo amancane kakhulu kanye nesondo elincane kakhulu ngaphambi kokushayela iketanga, ukuze iketanga libe likhululekile futhi kube lula ukulisebenzisa, futhi kungabi lula “ukugxuma” ngemva kokulinqamula.
Ngemva kokuba uchungechunge seluhlanziwe futhi lufakwe uphethiloli, phendula kancane kancane i-crankset ibheke phansi. Izixhumanisi zeketanga eziphuma ku-derailleur yangemuva kufanele zikwazi ukuqondiswa. Uma ezinye izixhumanisi zeketanga zisagcina i-engeli ethile, kusho ukuthi ukunyakaza kwalo akubushelelezi, okuyifindo elifile futhi kufanele lilungiswe. Ukulungiswa. Uma kutholakala noma yiziphi izixhumanisi ezonakele, kumele zishintshwe ngesikhathi. Ukuze kugcinwe uchungechunge, kunconywa ukuhlukanisa ngokuqinile phakathi kwezinhlobo ezintathu ze-pin bese usebenzisa ama-connecting pin.
Qaphela ukuqondeka lapho usebenzisa umshini wokusika uchungechunge, ukuze kungabi lula ukuphambukisa i-thimble. Ukusebenzisa amathuluzi ngokucophelela ngeke kuvikele amathuluzi kuphela, kodwa futhi kufeze imiphumela emihle. Ngaphandle kwalokho, amathuluzi angonakala kalula, futhi amathuluzi alimele angase alimaze izingxenye. Kuyindilinga embi kakhulu.
